css - Logo 在中间，菜单在右边

Question

我想在页面中央有一个 Logo ，然后在右边的 3 个菜单项上。我正在尝试像下面那样执行此操作，但它不起作用， Logo 不在页面的中心。你知道怎么做吗？

html

<header class="container">
    <div class="content-full main_header">
        <div class="logo">
            <a>LOGO</a>
        </div>
        <div class="menu">
            <ul class="main_nav">
                <li><a href="">Item 1</a></li>
                <li><a href=""><i class="fa fa-sign-in" aria-hidden="true"></i> Item 2</a></li>
                <li><a  href=""><i class="fa fa-plus-circle" aria-hidden="true"></i> Item 3</a></li>
            </ul>
        </div>
        <div class="clear"></div>
    </div>
</header>

CSS

*,
*:after,
*:before {
  margin: 0;
  padding: 0;
  box-sizing: border-box;
  -moz-box-sizing: border-box;
  -webkit-box-sizing: border-box;
  outline: 0;
}

a {
  text-decoration: none;
}

ul {
  list-style: none;
}


.container {
  float: left;
  width: 100%;
}

.content-full {
  width: 100%;
}

.main_header {
  border-bottom: 1px solid #d2d6df;
  color:$color-white;
  height: 60px;
  float: left;
  background-color: red;
  text-align: center;

}

.logo{
  line-height: 60px;
  text-align: center;
  background-color: yellow;
  display: inline;

}

.menu{
  display: inline;
  background-color: blue;
  text-align: right;
  float: right;

}

.main_nav li {
  float: left;
  line-height: 60px;
  text-transform: uppercase;
  border-left: 1px solid #EFF2F5;
  padding-left: 20px;
  padding-right: 20px;
  font-size: 0.8em;
  letter-spacing: 0.5px;
  border-radius: 0px;
}

.main_nav a {
  color: gray;
}


.main_nav .create{
  color:green;
}

.main_nav .create:hover{
  color:green;
}

Answer 1

添加菜单:

.menu{
  position: relative;
  top: -60px;

}

对于 DOM:

<header class="container">
    <div class="content-full main_header">
        <div class="logo">
            <a>LOGO</a>
        </div>
    </div>
    <div class="menu">
            <ul class="main_nav">
                <li><a href="">Item 1</a></li>
                <li><a href=""><i class="fa fa-sign-in" aria-hidden="true"></i> Item 2</a></li>
                <li><a  href=""><i class="fa fa-plus-circle" aria-hidden="true"></i> Item 3</a></li>
            </ul>
        </div>
</header>
